Title: Ic memory card
Inventor: MIZUTA MASAHARU
IPC: G06F21/79
Filed: 1990-02-27
Abstract: PURPOSE:To simplify the checker processing by operating AND between the signal indicating the open/close state of a write protect switch and a changed control signal, and outputting the result to the outside. CONSTITUTION:When a write protect switch 5 is open, a logic IC 11 outputs a write protect signal WP in the high level to the outside through a connector 2. When the write protect switch 5 is closed, a write control signal WE2 goes to the high level a prescribed time after going of the signal on a signal line 61 to the low level, and therefore, the logic IC 11 outputs the write protect signal WP in the low level after the prescribed time. Thus, the write protect switch 5 is opened and closed and the write protect signal WP at this time is verified to discriminate whether the write protect control surely acts on a memory IC 4.

Title: Controller for direct current motor
Inventor: NAGASE HIROSHI
IPC: H02P7/288
Filed: 1982-03-23
Abstract: PURPOSE:To control speed and torque stably by overlapping signals corresponding to deviation between current actual value and current command value to current command signals and controlling currents. CONSTITUTION:An error-section control circuit 15 outputs error signals between current command value corresponding to deviation between speed command outputted from a speed control circuit 11 and speed actual value and current actual value. A current control circuit 13 transmits deviation signals between signals obtained by adding current command value and outputs from the error- section control circuit 15 and current actual value to a chopper circuit 4 through a gate circuit 14. Accordingly, speed and torque can be controlled stably because currents in accordance with commands can be flowed at all times.
